Objective We aimed to explore the therapeutic mechanism of electroacupuncture at Yintang(EX-HN3),Neiguan(PC6)and Zusanli(ST36)on the Hypothalamic-Pituitary-Adrenal axis(HPA)of functional dyspepsia(FD)rats.Methods Forty SD rats were randomly divided into blank group,model group and EA group.The FD model was replicated by tail clamping,irregular diet,and filling the stomach with ice of Saline Solution.After modeling,the EA group received acupuncture treatment for 1 time day,30 minutes time,for 14 days.Recording the general state of the rat.Detection of locomotion and catatonia in rats by open field test.HE staining to observe the morphology and inflammation of gastric mucosa in rats.PCR detection of mRNA expression of 5-hydroxytryptamine3 receptor and corticotropin-releasing hormone in rat hypothalamus.Detection of corticotropin-releasing hormone receptor-2 and NOD-like receptor protein 6 inflammasome protein expression in rat duodenum by Western blotting.Alcian blue staining was used to detect the expression of rat duodenum goblet cells.Results Compared with the blank group,the general state,distance,speed,duodenum CRHR2 and NLRP6 proteins in the model group were significantly decreased(P<0.05),the hypothalamic 5-HT3R and CRH mRNA were significantly increased(P<0.05).Compared with the model group,the general state,distance,speed,expression of CRHR2,NLRP6 protein and goblet cells in the duodenum of rats in the EA group were significantly increased(P<0.05),the 5-HT3R and CRH mRNA in the hypothalamus were significantly decreased(P<0.05).In the model group,the connective tissue of the gastric mucosa was loosely arranged,the submucosa had mild edema,and there were some lymphocytes.The connective tissue of the gastric mucosa of the rats in the blank group and the electroacupuncture group was closely arranged,and there was no obvious proliferation of interstitial cells and no inflammatory cells.Conclusion EA can increase the expression of CRHR2,NLRP6 protein and goblet cells in the duodenum,and inhibit the expression of 5-HT3R and CRH in the hypothalamus.EA can improve gastrointestinal motility and locomotion,relieve anxiety,repair the mucosal barrier of the defective intestine,and restore the function of the Hypothalamic-Pituitary-Adrenal axis.

Objective:To explore the latent classes of health behavior and explore the predictive factors among stroke patients.Methods:A total of 1 250 participants were recruited using cluster random sampling in September 2022. The general information, the modified Rankin scale(mRS), stroke prevention knowledge questionnaire(SPKQ), health behavior scale for stroke patients (HBS-SP), and short form-health belief model scale (SF-HBMS) were administered in the cross-sectional survey. Mplus 8.3 software was used to conduct a latent class analysis (LCA) on the health behavior of stroke patients, and SPSS 27.0 software was used to carry out multinomial Logistic regression to analyze the predictive factors of different latent classes of health behavior of stroke patients.Results:The health behavior of stroke patients obtained three latent classes: low health behaviors-lack of health responsibility group (66.9%, n=794), moderate health behaviors-poor compliance group (11.9%, n=141), and good health behaviors-insufficient exercise group (21.2%, n=251). Compared with good health behaviors-insufficient exercise group, stroke patients with shorter duration education time ( B=-0.589, OR=0.555, P=0.036), hemorrhagic stroke ( B=0.082, OR=1.086, P<0.001), fewer comorbidities ( B=-0.022, OR=0.978, P=0.026), higher mRS score ( B=-0.046, OR=1.047, P=0.004), lower SPKQ score ( B=-0.055, OR=0.947, P=0.016), and lower SF-HBMS score ( B=-0.085, OR=0.919, P<0.001) were more likely to be included in moderate health behaviors-poor compliance group. However, stroke patients with shorter duration education time ( B=-0.026, OR=0.974, P=0.003), rural areas dwelling ( B=0.800, OR=2.225, P=0.004), fewer comorbidities ( B=-0.056, OR=0.945, P<0.001), lower SPKQ score ( B=-0.101, OR=0.904, P<0.001), and lower SF-HBMS score ( B=-0.071, OR=0.931, P<0.001) were more likely to be included in low health behaviors-lack of health responsibility group. Conclusion:The health behavior of stroke patients has three latent classes. A targeted intervention should be carried out according to the characteristics of different classes to improve their health behavior levels.

Objective:To evaluate the relationship between the mechanism by which aucubin improved attention deficit hyperactivity disorder (ADHD) induced by maternal exposure to S-ketamine and GABAergic neurons in the habenular nucleus of offspring mice.Methods:SPF healthy C57BL/6 wild-type pregnant mice were used in this study, and an ADHD model in offspring mice was established by intraperitoneally injecting S-ketamine in the middle and late pregnancy. Twenty-four offspring of pregnant mice exposed to S-ketamine were divided into 2 groups ( n=12 each) at 14 days after birth using a random number table method: ADHD + normal saline group (AN group) and ADHD + aucubin group (AA group). Twenty-four offspring of pregnant mice exposed to normal saline were divided into 2 groups ( n=12 each) at 14 days after birth by a random number table method: control + normal saline group (CN group) and control + aucubin group (CA group). Aucubin 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in CA group and AA group, and the equal volume of normal saline was given instead in CN group and AN group. At 14 days after birth, the 16-channel microfilament array electrode was placed in the habenular nucleus, and the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was recorded when the mice buried beads in the marble burying test. At 21 days after birth (after the end of peritoneal administration), the impulsive and stereotypical behaviors of offspring mice were evaluated by elevated zero maze and marble burying test, respectively, and then the expression of glutamate decarboxylase 2 (GAD2) in habenular nucleus was detected by the immunofluorescence method. Results:Compared with CN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly increased, the expression of GAD2 was down-regulated, the time spent in the open arm was prolonged, the number of entries into the open arm and the number of buried beads were increased in AN group ( P<0.05), and no statistically significant differences were found in the above indexes in CA group ( P>0.05). Compared with AN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly decreased, the expression of GAD2 was up-regulated, the time spent in the open arm was shortened, and the number of entries into the open arm and the number of buried beads were decreased in AA group ( P<0.05). Conclusions:The mechanism by which aucubin alleviates prenatal S-ketamine exposure-induced ADHD may be related to increasing the number of GABAergic neurons in the habenular nucleus of offspring mice.

OBJECTIVETo compare the efficacy and adverse events of adjusted BACOD (bleomycin, doxorubicin, cyclophosphamide, vincristine, dexamethasone) regimen (continuous intravenous infusion) and conventional BACOD regimen (conventional intravenous drip) in the treatment of relapsed and refractory diffuse large B cell lymphoma (DLBCL).

METHODSRetrospective analysis of 63 cases of relapsed or refractory DLBCL patients was performed, 32 patients received conventional BACOD regimen and 31 patients received adjusted BACOD regimen.

RESULTSThe response rates for adjusted group and conventional group were 87.1%(27/31)and 62.5%(20/32), respectively, during a median follow-up of 14(7-84) months. The difference was statistically significant between the two groups (P=0.025). The main adverse events were myelosuppression, gastrointestinal adverse reactions were rarely serious, and there were no serious liver and kidney toxicity. The median overall survival (OS) was 33 months for adjusted group and 12 months for conventional group, there was statistical differences (P=0.019). The median progression free survival (PFS) was 11 months and 8 months for two groups, the difference was not statistically significant (P=0.095). 1-year survival rates were 68.8% for adjusted group and 44.3% for conventional group, there were no statistical differences (P=0.055). The expected 3- and 5-year survival rates of adjusted group were significantly higher than that of conventional group (47.1% vs 12.8%, P=0.002; 37.7% vs 8.5%, P=0.006, respectively).

CONCLUSIONCompared with the conventional BACOD regimen, the adjusted BCOAD regimen is effective and well tolerated in patients with relapsed or refractory DLBCL, the overall response rate and OS increased.
